7.1.2.12 Thread tension settings and tolerances
Defines the limit of the thread tension which is measured by the thread tension sensor.
In this section there are optional settings for an additional tolerance of the thread ten-
sion. If the option of setting max. NOKs and max NOKs in a row are granted as user
rights then you can select the settings. Please use these settings carefully as they have
a great impact on your product quality. The meaning is as follows:
Max NOKs – define how many not okay stitches (by their thread tension values) are al-
lowed in the safety seam. E.g. you define 2 stitches as max NOKs, then if 7th
s
, 8th, 9
th
stitch is out of limits then the system stops and declares the part as not okay.
Max NOKs in a row – define how not okay stitches (by their thread tension values) are
allowed in the safety seam in a row. E.g. you define max 2 stitches as max NOKs in a
row then if the 7th
s
, 8th, 9th stitch are out of limits then the system stops and declares
the part as not okay.
